Single Snapshot Direction of Arrival(DoA) Estimation Using Variant Min-Norm Method
Devika Rajeswaran · 2018
High resolution algorithms for angle estimation is essential to achieve resolution of targets in radar systems. Major drawback of existing subspace based algorithms is that its performance gets degraded for reduced number of snapshots. When number of snapshot is less than number of sources, resolution offered by subspace based algorithms are very less. A new algorithm (variant min-norm method) to achieve accurate direction of arrival estimates in single snapshot radar scenario is proposed in this paper. This paper investigate and compare different subspace based algorithms with the proposed algorithm in terms of single snapshot performance. Main objective of this work is on improving the angle estimation accuracy and resolution offered in a multi target environment.
